Cats cannot get human AIDS, but they can get their own version called FIV (feline immunodeficiency virus), which people often nickname “feline AIDS.”

Can cats have “AIDS”?

  • Cats are infected by FIV , a lentivirus that damages their immune system in a way that is broadly similar to how HIV affects people.
  • When FIV infection becomes advanced and the immune system is badly weakened, vets sometimes refer to this stage as “feline AIDS.”

Can cats give AIDS to humans?

  • FIV only infects cats; HIV only infects humans, and the viruses do not cross between species.
  • Living, cuddling, or sleeping with an FIV‑positive cat is not a risk for human HIV/AIDS or any human version of the disease.

How do cats catch FIV?

  • FIV is mainly spread by deep bite wounds, usually during fights, so unneutered outdoor male cats are at highest risk.
  • Transmission from an infected mother to kittens is possible but relatively uncommon, and casual contact like sharing bowls or grooming is a low‑risk route.

What happens to a cat with FIV?

  • Many FIV‑positive cats stay clinically well for years, and some never progress to full “feline AIDS.”
  • As the immune system weakens, they become more prone to infections, dental disease, weight loss, and other illnesses that need prompt veterinary care.

Protecting your cat

  • Keeping cats indoors, neutering them, and avoiding fights with unknown cats greatly lowers the chance of FIV infection.
  • If you’re worried about your cat, a simple blood test at the vet can check for FIV, and many infected cats can still live long, comfortable lives with good management.
